This invention relates to signaling systems in general, but, more. particularly, to such systems wherein the signals are transmitted from one or more sending stations tomemotely disposed receiving stations, the signals comprising series of impulses corresponding to digits of numbers. n

The system of my invention, to be disclosedin detail subsequently, is particularly adaptable for use in newspaper printing plants to convey information to the varlous branches of the-plant concerning the status of the making of the matrices, so that the printing of the newspapersmay be completed in the shortest period of time posslble and with the least 'number of delays.

Briefly, as news is set into type by the linotype machines, the forms for the sheets of an edition of the newspaper are made up from the lines of type from the machines. When a form is completed, it is sent to thel foundry and a -inold is made thereof From the mold, the matrices are cast and as com- 5o. to simultaneously notify thevarious rooms pleted, are sent to the electrotyping room where they are finished and bent into shape to fit the cylindrical presses. Each matrix is inspected when finished and either passed or rejected.. lf rejected, the matrix is returned to the foundry and either repaired or scrapped, a new one being made in'case the other is sera pecl. If passed, the matrix will be sent to tlpie pressroom.

In the pressroom, the printing presses are scheduled to run certain sheets of an edition. Therefore, it can be seen that it is of vital importance to the pressroom to know when a certain matrix has passed inspection, because the pressroom will know from that how long it will be. before the matrix is received in the pressroom. v c

The information concerning inspection is also of importance to the linotype room, to the foundr and to the electrotyping room. It is, t erefore, the duty of the inspector to notify these rooms as he finds a matrix to be satisfactorily constructed.

Accordingly, I have assumed as the principal object of my invention, the prpv-ision o a system which will allow the inspector ytime is of great importance.

in a reliable, speedy, and accurate manner, that a matrix has passed inspection.

In actual practice, there are so Imany matrlces passing through inspection that it vwould be impractical'for the inspector to stop after each inspection and notify the various rooms since, in the newspaper printing business, a matter ofa small period of Therefore, a signaling operator is usually employed for the purpose ofv transmitting the information, and, in the case of large. newspaper plants, more than one roperator is often necessary. Therefore, I have shown the sys. tem of my invention as employing two operators.

The kvarious features and other objects not specifically mentioned herein, will be apparent from the detailed description to follow when studied in conjunction with the accompanying single sheet of drawing, which, by means o the usual symbols, presents the system of my invention in diagrammatic form, only such equipment being shown astwill enable the reader to obtain a complete understanding of the operation and adaption of the system.

The two operators positions, or transmittin stations, are shown at the left-hand side o the sheet of drawin to the left of the dotted vertical line, an are designated on the Ydrawing by transmitting station No. 1 and transmitting station No. 2. Each of these stations isprovided with a plurality of keys and signal lamps Whose functions Awill be pointed out subsequently. In addition to these, each transmitting station is rovided with an impulsing device S havmg the shunt springs 1 and 2 and the` impulse springs 3 and 4. The impulsing device S is of the finger dial type familiar to those skilled in the art. It is thought necessary to only point out thatthe shunt springs 1 and 2 of the device are operated when the finger dial is turned from its normal position and remain in engagement until the finger dial has returned to itsrnormal position., and that the impulse springs 3 and 4 are only operated with the return-to-normal movement of the finger dial.

Since the selector E associated with transmitting station No. 2 is identical with the selector E associated with station No. 1, only the relay 5 and the springs controlled thereby have been shown smce the operation of the selector E will be readily understood :from a description of the operation of the selector E.

Selector E has two wipers, 31 and 32. The wiper 31 is elevated by the action of the vertical magnet of the selector and is then rotated by the action of the` rotary magnet. The bank of contacts accessible to the wi er 31 is arranged in ten horizontal rows o ten contacts each, in the well known manner. The wiper 32 is elevated by the action of the vertical magnet and is also rotated under the action of the rotary magnet. Wiper 32 has access to only ten contacts which are arranged in a single, vertical row. The .rotary movement of wlper 32 disengages the wiper from whatever contact it is in engagement with as the result lof the vertical movement.

The selector E is provided with two banks of contacts identical with those to which wipers 31 and 32. of selector E have access. Corresponding contacts in the banks of selector E are multiplied to correspondingicontacts of the banks of selector E.

In the upper right-hand corner of the drawing is a dotted rectangle which represents one of the register panels.v This panel is provided with one hundred and ten signal lamps, one hundred of which are associated with the bank to which wiper 31 has access, while the other ten are associated. with the bank to which wiper 32 has access. The circuit of each lamp 40 is controlled by a relay similar to relay 34. Therefore, there will be one hundred and ten such relays. Each of the ten relays associated with the ten lamps which, as" said before, are associated with the contacts accessible to wiper 32, has its winding connected to one of the contacts accessible to wiper 32 of each of the selectors. Thus, each of the ten relays ma be operated from either ofthe selectors.

Each of the other one hundred relays has its winding connected to one of the contacts of the banks accessible to Wiper 31 of each of the selectors, and may be ope-rated through either of the selectors.

l Since, as previously stated, it is important that each of the various rooms be notiiied when a matrix has passed inspection, each of thoserooms will be furnished with a register .the face of 4wiper 31 has been panel similar to that just described. In order that a signal may be registered upon all panels simultaneously, the windings of all corresponding relays will be connected in parallel to the bank contacts as indicated by the arrows on conductor 43.

he arrangement of each register panel is such that when one of the signal lamps is lighted, it will cause to be exposed on the panel any symbol which ma be required by the particular use to whic the system is employed. Lamp anels of this character are well known an need no further explanation. In the present s stem, anyone of the lamps associated with the banks accessible to Wi er 31 will expose numerals to indicate tlie page number of the edition of the newspaper, and anyone of the ten lamps associated with the banks accessible to wiper 32 will cause the exhibition of letters corresponding to the various names of the editions.

In describing the operation of the system, it will be assumed that operations for the day at the printing plant are about to begin. In Athis case, the matrices for the first edition of the paper will be in the process of manufacture. ting station No. 1 will, as his first operation display on the register panels the name of the edition about to go to press. In order to do this, he will first operate his start key SK and then operate h1s impulsing device S to operate the selector E to raise the wiper 32 to the contact associated with the The operator at transmitlamp of the register panel which will exl hibit the name of the edition. Having done -this, h e will then release the start key SK,

which release causes the release of selector E. As selector E releases,.it completes the circuit of the relay connected to the contact upon which wi er 32 is restin The operation of the re ay, such as re ay 34, lights the lamp to exhibit the name of the editlon.

As each matrix is passed by the inspector,

the operator will operate the start key and y, operation of the relay vassociated with the contacts into engagement with which the laced. Since the rela is not operated untll the switch is release the operation of wiper 32, in accordance with the first di it of the number of the matrix, has no eect since it is rotated out of engagement with its bank contacts by the olperation of the selector in accordance with t e second digit of the number of the matrix.

10, it has passed inspection that it tion No. 1 can, by the operation o A general The matrices for pages 10 to 99, inclusive, of the edition, bear the number corresponding to the number of the. pa e. In order A toravoid operation of relays t rough wiper 5 32 when transmittin Should a matrix' become so dama ed after as been found necessary to make a new one or to have it repaired, the operator at the transmitting station will indicate this by causing the registration on the panel, corre- 15 s onding to that matrix, to be wiped out.

his operation `will be described in detail subsequently. When all matrices for an edition have passed inspection and have been received by the pressroom, the o ratpr mayl .20 by the operation of his key CW wlpe out registrations on all of the panels. AThis operation also will be described subsequently.

Should the selector E get out ofoperating order, the operator at transmittin sg:-

e change-over key COK, use the selector E associated withI transmitting station No. 2, provided that at that time the selector -E is not inv use.

description ofthe operation of the system,having been given, la vdetailed description'thereof will now be, gwen.

Assume that the signal lampy 1n the register panel shown is the lamp whlch the 35 operator wishes tov light to exhibit on the panel the name of the edition about. to. go to print. It will benoted that the winding of relay 34 is connected to the first contact in the bank of wiper 32.l Therefore, in order to select lamp 40, the selector E must be operatedto-raise its wiper 32 one step. To

do this, the operator will depress the start key SK and hold this key depressed while he is manipulating the impulsing device. The operation of key. SK completes the circuit for relay 10 in vseries w1th the lowerl winding of relay 16 by way of resistance element. R and armature 6 and resting contact of relay 5. Resistance element R is of such value that relay` 16 will not secure enough current through that resistance to energize' Relay, 10 energizes, however, and 4 attracts its arsuiiiciently to attract its armature.

matures. t armature 11 of vrelay 10, the circuit of relay 8 is completed from ground by way of the spring contacts of'the lstart key, impulse springs 3 and 4, armature 7 of relay 5 and its resting contacts, and rmature 11 and its make contact. At armature l2 of relay 10, the impulsing circuit of the selector is prepared. xAt armature 13 the obvious circuit of relay 26 is comleted. At armature 14 of relay 10 a vpoint 1n the circuit of wipers 31 and 32 is opened.4 QRelay 8 energizes when its circuit'is com- 24 to battery. Vertica pleted, and lop-ens'the impulsing circuit at 30, inclusive, at armature 27, closing a point in the circuit of the wipers 31 and 32 at armature 28 removing ground from thefrelease magnet circuit, at armature 29 preparingthe impulsing circuit, and at armature 30 completmg the circuit of the 1am 41 at the transmltting station No. 2 to in icate to that station that the selector E is'in use.

lnV order to operate the selector E to raise the wipers one step, the operator inserts his fin r in the No.' 1 hole of the finger dial an turns the dial from its normal osition. As the "dial is turned loff-norma shunt springs 1 and 2 engage to connect-ground to the impulsing circult, which ground ,will be independent of that furnished by key SK. When the finger dial is released and allowed to return to normal, the im ulse cam causes-a momentar separation 0 imtary opening of the circuit of relay 8'causes the armature 9 thereof to momentarily complete the im ulsing circuit, this circuit being completed rom ground by Way of armature 29 of relay 26, esting contact in armature 9, armature 1 and its make contact', off-normal springs 21and 19, winding of series relay 22, windin` of vertical magnet l magnet 24 momentarily operates and, in so doing, elevates the, wipers 31 and 32 one step, placing wiper 31 opposite the first horizontal row of contacts and placing Ywiper 32 in engagement with the first contact of its bank. The elevation of the wipers causes' the operation of the vertical off-normal springs. When this occurs, springs 21 and 19 will disengage and springs 2O and 21 will engage each other, while springs 37 and 38 in the release magnet circuit engage each other'.

If the circuit of relay 8 had been openedv a number of times momentarily, aplurality f of impulses would-have been transmitted to the vertical magnet. Relay 22 being a slow l to release relay because of the copper slug on the heel endof its core, after energizing in series with the vertical magnet 24 on the rst impulse, remains in its ener ized position throughout the plurality o impulses,

and returns to its deenergized'fposition shortlyafter the termination of. the last impulse of the series.- After the first vertical step of the wipers, that is after the impulse springs 20 and 21'have come into engagement with each other, the impulse circuit now will include springs 21 and 20 and armature 23 and its make contact.

After the operation of the calling device by the operator,- the start key SK is released and consequentlythe circuits of relay 10 and from battery by way relay 8 will be open. Relay 1Q upon releasingretracts its armature 14 topomplete a and resting contact of relay 10, armature 27 and make contact of relay 26, wiper-32, the

first contact in the bank of'w er 32, conductor 43 to` round through t e winding of relay 34. t should be noted here that,

although at its armature 13 relay.1 0 opens the circuit of relay 26, relay 26 because of the copper slug on the heel end of its core, maintains `its armatures in the attracted position for a short interval after its circuit is opened. Thisinterval is long enough,

however, to allow the relay 34v to energize.

Relay 34 upon energizing, at its armature 36 completes a locking circuit for itself through the non-inductive resistance NI to conductor 44 and at its' armature 35 com- .pletes the circuit for the signal lamp 40 to exhibit the name of the edition on the panel.

When relay 26 deenergizes, it retracts its armatures, thereby at armature 28 complet ing a circuit for the release magnet 15. Although the circuit for the release magnet 15 is completed in series with the relay 34, release magnet 15 is marginal and does not receive suiiicient current in series therewith lto cause it to operate. When the release magnet circuit is completed by wa of arma, ture 28 and its resting contact, t e selector E will release and the wipers 31 and 32 will be returned to their normal positions. This return to the normal position of the wipers opens the off-normal springs 37 and 38 and closes the off-normal springs 19 and 21. The impulsing circuit is also opened by the release of relay 26. The circuit for the lamp 41 at the transmitting station No. 2 is also opened by the release ofrelay 26 to indicate that the selector E is no longer in use.

Since the relay 34 at the register panel is locked in its energized position, the circuit for tne signal lamp 40 will be maintained completed until some operation is performed to release the relay 34.

When a matrix passes inspection, the inspector notifies the o erator of the number of that matrix, in ot er words, the number of the page of the newspaper, and the oper:

ator then, operates his lmpulsing device in accordance with the digits of that number, operating first his start key SK and holding the key SK depressed throughout the operation of the impulsing device.

In accordance with the number of impulses comprising the first digit of the number of the matrix, the selector E raises its wipers 31 and 32 a corresponding number of steps. ,After the last impulseof the first series has been received by the vertical magnet 24, the series relay 22 deenergizes and yone hundred and ten signalsI t e circuit of the rotary magnet 25.

In accordance with the number of impulses in the series corresponding to the second digit of the number of the matrix the rotary magnet rotates the wipers 31 and 32 a number of ste correspondmg thereto. The rotation of wiper 31 moves it into engagement with the contact of its bank corresponding to the number of the matrix. The rotation of wiper 32 moves -it out of enga ent with the contact of its bank.

battery through the release magnet 15 is again connected by way of armatures 14 and en the selectorA is released as before,A

27 to the wipers 31 and 32. Since wiperl Since'there are three other panels similar to that shown, the connection vof battery to wiper 31 operates the other three rela sas was just described for the one relay.

'b the retraction of its armature 23 prepares l on the panel the number of I hus the numeral, or matrix number, is simultaneously displayed upon the four different panels. The return of the selector E to its normal position is completed as explained when the relay 26 deenergizes toV complete an independent circuit for the ,release magnet 15. v

Inasmuch as it is unlikely that the two operators at stations No. 1 and No. 2 will ever desire to transmit the same number, it is possible for both' operators to set up numbers on the same panels at the same time.

Since there are one hundred relays in each panel connected to the bank of wiper 31, and since there are ten relays in each panel connectcd to the bank wiper 32 there can be displayed upon each panel at one time. Since it is unusual for a newspaper to have one hundred and ten pages 1t is unlikely that Aalllof the signals on the lamp panel will be' lighted at one time.

In the case where a matrix becomes damaged and the operator desires to' wipe out the numberjof that matrix if it is on the panel, he can do so by operating the single number-wipe-out key IWK and operate the impulse device Sin accordance with the number of that matrix. By operating the` l order, the operator at I over key bank corresponding to -to the operator that his change-over after its circuit has been completed by relay As before, the selectorE responds to the impulses of the series to osition its wiper 31 in engagement with tie contact of its the number ofthe matrix. Since relay 16 is locked in its energized position, armature 17 is held in engagement with its .grounded make contact. 'l`herefore,'when rela 1() deenergizes upon the release of key IW ground is connected to wiper 31 in place of battery throu h the release magnet. The connection o this ground to wiper 31 short circuits the windings of relays similar to relay 34, which relays then deenergize and open the circuit of their associated lamps and also their own locking circuits, thereby wiping out the numerals correspondingI to the damaged matrix from the several register panels.

After the last matrix has passed throu h the inspection and been received in t e pressi-oom and before the matrices for another edition commence to pass the inspec' tion, it will be necessary to wipe out all of the registrations on the register panel.. To do this, each sending station has been provided with a complete-wi e-out key GWK, the operation "of anyone o which completes the circuit fory relay 33. Relay 33 operates and attracts its armature, thereby removing battery from the common locking conductor 44. All of the relays, suchas relay 34, which are locked up to the common'locking conductor 44 deenergize when the battery is removed therefrom. As each relaydeenergizes, it opens the circuit of the signal lamp associated therewith to wipe out-the registration on the panel.

Should the selector transmitting station No. 1 may use the selector E b operating the change-over key COK.- Be ore operating Athis key, the operator will look at lamp 41 at his station to see if the selector E isA in use. If selector E is in use, lamp 41 will be lighted, having been lighted in a manner similar to that in which lamp 41 at station No. 2 was li hted. The operation of changefor lamps 42 and Lamp 42 at station 42 and relays 5 and 5. No. 1 lights to indicate key COK isin the operated position` Lamp 42 at station No. 2 indicates to the o erator 'of that station that his selector E is Eeing used by the operator at station No. 1. Relay 5 operates when its circuity is completedand attracts E get out of operatir'ig` OKv completes parallel 'circuits its armatures 6 and?? into engage-said switch in response ment with their alternate contacts, thereby connecting the impulse device S and start key SK at station No. 1 with relays 8 and 10 of the selector E. The operator at station No. 1 now proceeds as in the o eration of selector E to operate selector The release of change-over key OOK extinguishes the lio'hts 42 and 42 and disconnects station No. 1 from selector E.

The operation of relay 5', following the operatiomof changeover key COK at station No. 1, disconnects the impulse device S at station No. 2 from selectorh E' so-that the l operator at station No. 2 can in no way mutilate the operation of'the'selector Eby stationkNo. 1.

The operation of change-over'keyCOK at station No. 2 lights the signal lamps 42 -and 42 for the purposelalready explained, operates relay 5 to disconnect the im ulse device at station No. 2 from selector E and connect it to selector E, and operates rela 5 to disconnect impulse devi'ce S of station o. 1 from the selector E to prevent mutilation of signals from transmitting station No. 2.

It will now beappreciatedlthat, by providing two groups of lamps, one group of ten lamps lamps, and a two-motion selector switch having access to the ten lamps througha vertical wiper and having access to the one hundred lamps through a rotary wiper, a plurality of signals ofv the order of three digits can be registered by the transmission pf signals corresponding to two digits when all of the signals are of the same orderof three digits.` More explicitly, thousands digit 'has` been registered, as many as one hundred signals of that thousands order can be registered withoutthe necessity of registering the thousands digit for each' of the hundred signals. 5In the instant embodiment, the"thousands digits are used to display the edition nomenclature. This -display in a different embodiment could be in the form of numerals, or-other characters, merely by changing the register pane l Although I have descr'bed the system of my invention in its preferred application,

exactv foregoing disclosure since there are undoubtedly modifications and adaptions which can be made by` those skilled in the art without departing from the spirit and sco e of the invention.V

aving thus described my invention, what 1' consider new and what I desire to have protected by Letters Patent will be .pointed out in the claims which follow.

What is claimed is: A
